I’ve had my Sense for 2+ weeks now, and at night, it’s telling me my power consumption does not go below 600 W. Been scratching my head as to what could possibly be drawing that much power but to no avail. I have several always plugged-in devices (smart switches, lighted GFCI outlets, fridge/freezer, security cameras, landscape lights, …). I listed all in Excel, and added up their rated/max power, and came-up very short of the 600W.
I’ve read in another thread that some houses have ‘constant-on’ devices such as an attic fan that draw 200W … but can’t think of any such thing in my house.
Any thought as to what could be drawing so much power … or maybe some errors with the Sense?
I’m leaning to two possible culprits:
- The Sense CTs are not properly calibrated (long shot)
- Something else at home drawing power … and can’t figure out what it is.
How do I solve this? Well, been thinking of 2 approaches:
- I have the extra CTs for monitoring 2 additional circuits … I could move those around, two circuits at a time, and monitor their draw over 2 hours. That will take a lot of time as I have about 30 breakers and no guarantee I can catch the power hogs, especially if their power draw is intermittent/transient.
- Invest in a second monitor (made by a competitor of Sense) that uses 16 CTs, and monitor many of the circuits all at once.
